NOTES: 1 Assumes a heatsink thermal resistance of less than 2,0C/watt. 2 Non-tepetitive voltage and current ratings, as contrasted to repetitive ratings, apply for occasional or unpredictable overloads. For example, the forward surge current ratings are non-repetitive ratings that are used in fault coordination work, 3 Assumes a heatsink thermal resistance of less than 1.0C/watt. 4 Pic-Pac is an acronym for Pressure Internal Contact Package. 577MAXIMUM ALLOWABLE PEAK FORWARD CURRENT-AMPERES MAXIMUM ALLOWABLE PEAK FORWARD CURRENT-AMPERES DEVICE SPECIFICATIONS INSTANTANEOUS FORWARD CURRENT-AMPERES 10,000 5,000 2,000 500 200 100 50 Ty = 125C Ty #25C 0 1.0 : zx : INSTANTANEOUS FORWARD VOLTAGE-VOLTS 1.
